Overview SOLID is an acronym for five design principles intended to make software designs more understandable, flexible, and maintainable. Core Concepts S – Single Responsibility Principle (SRP): A class should have one, and only one, reason to change. It should perform only one job. O – Open/Closed Principle (OCP): Software entities should be open for…

Overview Object-Oriented Programming (OOP) is a programming paradigm based on the concept of “objects”, which can contain data (attributes/properties) and code (methods). It aims to implement real-world entities like inclusive objects to make the codebase more modular and intuitive. Core Concepts Class: A blueprint for creating objects. Object: An instance of a class. Encapsulation: Bundling…

Overview This topic compares two primary architectural styles for building applications: the Monolith (a single, unified unit) and Microservices (a collection of small, independent services). Core Concepts Monolithic Architecture: Unified: All business logic, data access, and UI are in one codebase. Pros: Simple to develop, test, and deploy initially. Low latency between components. Cons: Becomes…

Overview Inheritance and Polymorphism are two core pillars of OOP that allow developers to create generic interfaces and reuse code efficiently. Core Concepts Inheritance: A mechanism where a new class (Derived/Child) inherits properties and methods from an existing class (Base/Parent). This represents an “is-a” relationship. Method Overriding: When a child class provides a specific implementation…

Overview Design patterns are typical solutions to common problems in software design. They are like blueprints that you can customize to solve a particular design problem in your code. They are not finished designs, but templates for how to solve a problem. Core Concepts Creational Patterns: Deal with object creation mechanisms, trying to solve the…
